High power supply rejection
WebSep 7, 2024 · An external capacitor-less ultra low-dropout (LDO) regulator that can continue to provide high power-supply rejection (PSR) over a wide range of the load current is proposed. Webreject AC-ripplevoltage on the power supply bus, as opposed to a DC specification where we measure the change in output voltage for a change in supply voltage. Basically, ripple PSRR is the ratio of the differential output voltage to the supply ripple voltage expressed in dB as shown in Equation 1. (1) Figure 2. PSRR Measurement Test Circuit
High power supply rejection
Did you know?
WebDec 18, 2024 · The power supply rejection ratio, or PSRR, has been steadily becoming more important due to the rising demand for power efficiency in electronic designs large and small. It’s a measure of how much disturbance signals have been injected at the input levels, which, in turn, can impact the regulated output. In electronic systems, power supply rejection ratio (PSRR), also supply-voltage rejection ratio (kSVR; SVR), is a term widely used to describe the capability of an electronic circuit to suppress any power supply variations to its output signal. In the specifications of operational amplifiers, the PSRR is defined as the ratio of the change in supply voltage to the equivalent (differential) output voltage it produces, often expressed in decib…
